Easy "Dirty Laundry" achievement

When you case Sal Al Din in the "Bump In The Night" mission, there will be a door to your left (an AKM gun will be on the floor next to it) that will display a prompt to open it when standing next to it. Open the door, and search the back of the room to find the grenades on a table and get the "Dirty Laundry" achievement.

Easy "Double Header" achievement

At the beginning of the "Changing Tides" mission, you will need to kill two enemies stealthily. Instead of using the melee attack, line up the two enemies so you can kill them both with one bullet to get the "Double Header" achievement.

Easy "Leftover Lead" achievement

When attempting to get the "Leftover Lead" achievement, make sure you compensate for bullet drop. Thus, you must aim a little above targets that are further away. You only have to shoot the targets that are highlighted with a red triangle; you do not need to worry about the other targets.

Easy "On The Clock" achievement

When attempting to get the "On The Clock" achievement in the "Through The Eyes Of Evil" mission, make sure you get head shots to get under 18 seconds. Each head shot will reduce your time by six seconds. If you run out of ammo with your primary weapon, switch to your secondary weapon to save time.

Easy "Storm Watch" achievement

When you enter the sandstorm in the "Hello And Dubai" mission, avoid all vehicles until you reach the exit ramp. If you do not get the "Storm Watch" achievement when you are on the exit ramp, pause the game, and restart from the checkpoint to try again.

Easy "Tactical Toggler" achievement

When you are in the helicopter giving ground support, shoot 25 enemies to get the "Tactical Toggler" achievement.

Easy "Tag, You're It" achievement

The following video is a strategy on how to catch Faraz within 15 minutes in the "Finding Faraz" mission. Try avoiding enemies and using both your primary and secondary weapon to save time.

Easy "Target Practice" achievement

When you enter the cave in the "Connect The Dots" mission, shoot all the targets in the training camp caves to get the "Target Practice" achievement. It does not matter if they are head shots or the targets are completely destroyed.

Easy "The Axeman" achievement

At the beginning of the "Changing Tides" mission, you must melee an enemy. Simply keep reloading the beginning of the mission to easily get 25 melee kills and "The Axeman" achievement.

Once you are out of the back roads and onto the local streets in the "Hot Pursuit" mission, there will be market stalls on your left-hand side. There will be about ten of them. Simply run into them with your vehicle. When the mission fails, keep repeating this process until you get the "Vender Bender" achievement.
